PIE CONTAINER
Abstract
A container having a base and a lid which are capable of being
releasably coupled at their outer circumferences. The base and lid
are constructed of a lightweight, semi-rigid material. The base is
deformable, within limits, in response to the pressure applied
thereon but will return to its original shape when the deforming
force is removed. Inclined, stepped sides extend from the bottom of
the base and form a plateau to accommodate and support a pie tin
and to hold the edges of the container extending past the rim of
the pie tin away from the pie crust, filling and topping. When
pressure is applied to depress opposite sides of the base at the
top the base deforms to squeeze against the slanted sides of a pie
tin therein, thereby raising the pie tin above the plateau such
that a users fingers can be moved under the edge of the pie plate
to lift it from the base.

Description
BRIEF DESCRIPTION OF THE INVENTION
1. Field of the Invention
This invention relates to containers for the housing, storage and
transportation of pies and the like.
2. Prior Art
The need for packages in which pies prepared for commercial sale
can be stored, transported and displayed has long been recognized.
In the past, cardboard boxes have been used for such packaging and
many times plastic window inserts have been provided in the boxes
so that at least a portion of a pie inside can be viewed without
opening of the box. The cardboard boxes are inexpensive and do
provide some protection for the product inside during storage and
transport, but they cannot be sealed so as to restrict air passage
and they lack structural strength so that filled boxes cannot be
stacked one on top of another to the extent desired and a box and
its contents are frequently crushed. Frequently, it is difficult to
open the cardboard box and to remove a pie therein without sticking
a finger in the pie or without damaging the pie edges. Also, in the
event the pie tin and contents slides to one side of such a carton,
the peripheral crust and pie topping are apt to be damaged.
The cardboard boxes, while providing a measure of protection for
the product therein are seldom very attractive and even if provided
with plastic window inserts do not attractively exhibit pies placed
therein.
The present invention provides a container which is specifically
constructed to house and display a pie type food product and that
overcomes the deficiencies inherent in the package previously
used.
SUMMARY OF THE INVENTION
Principal objects of the present invention are to provide a
low-cost container in which a pie-like food product can be stored
and transported and from which the product can be easily
removed.
Another object is to provide a container having base and lid
sections that can be releasably connected such that the connected
sections are sufficiently sealed that the passage of air into the
container interior is restricted.
Still other objects are to provide a container that will
attractively display a pie-type food product and that has
sufficient structural strength to allow for safe stacking of the
filled containers.
Principal features of the present invention include a plastic base
and a plastic lid (preferably transparent) that can be releasably
connected at their circumferences is such a manner as to
effectively reduce the admission of air into the container
interior.
The base has a bottom and a lower section wherein a slanted side
wall extends upwardly and outwardly therefrom with an intermediate
step therein forming a plateau spaced above the bottom of the
container. A pie tin, whether of aluminum foil or other material
fits snugly within the slanted side wall and the outermost lip of
the tin rests on the plateau and cannot slide with respect thereto,
even if the container is tipped somewhat. The side wall, above the
plateau, is spaced sufficiently far from the outermost periphery of
the pie tin that it does not engage a pie crust on the lip of the
tin and extends sufficiently upwardly that the lid section placed
thereon does not engage any filler or topping on the pie. The base
section is constructed of a deformable plastic material so that
when opposite sides of the wall of the section are depressed,
portions of the wall between the depressed sides pull inward to
squeeze the inclined surface of a pie tin contained therein. This
pushes the pie tin upwards until the user can insert his fingers
under the outermost flange of the tin to lift it from the base.
When the depressing pressure is removed from the side wall, the
base returns to its original assigned shape.
The lid section is constructed of a lightweight, semi-rigid plastic
material, such as a plastic, in which various designs, lettering,
or symbols may be molded, and is preferably transparent, so that
the container contents may be viewed.
Additional objects and features of the invention will become
apparent from the following detailed description and drawings,
disclosing what is presently contemplated as being the best modes
of the invention.

DETAILED DESCRIPTION
Referring now to the drawings:
In the illustrated preferred embodiment the container, shown
generally at 10, is round and consists of a lid section 11 and a
base section 12. The lid section 11 is shown as having a depression
13 formed in the center of a top surface 13a. The ridge forming the
depression adds strength to the lid and the depression is shaped to
receive the bottom of the base of a similar container stacked
thereon. The depression thus helps to stabilize stacks of the
container.
Lettering or writing or a design may be formed in the lid to
advertise the source of the food product housed therein or for any
other desired reason.
The base section 12 has a bottom 14 and a side wall 15 which is
inclined upwardly and outwardly from the bottom to accommodate the
inclined sides of a pie tin 16, as shown best in FIG. 4. The wall
15 is stepped to form a plateau 17 intermediate the height of wall
15 and above the bottom 14. The outermost flange or lip 16a of pie
tin 16 rests on plateau 17 and the inclined wall 16b of the pie tin
engages and rests on the wall 15.
A lip 18, which extends around the outer circumference of the base
section 12, is adapted to fit into a groove 19 which is formed in
the outermost flange 20 of a depending circumferential wall 21 of
the lid section 11. When the lip 18 is within the groove 19, the
container is effectively sealed against entry of air. However,
because of the natural resiliency of the plastic from which lid 11
is constructed the flange 20 can be pulled to release it from the
lip 18.
As shown in FIGS. 5-7, it is a simple matter to remove a pie tin
(and a pie therein, not shown) from the container 10. The lid
section 11 is removed, as has been heretofore described, and the
user pushes down at the top on opposite sides of the side wall 15.
The side wall 15, between the points at which the downward pressure
is applied squeeze against the inclined wall 16b of the pie tin 16.
This forces the pie tin up until the user can position his fingers
beneath the outermost flange 16a of the pie tin and between the
flange 16a and the plateau 17.
The pie tin and its contents are firmly supported by the side wall
15 and plateau 17 during transport, storage and display and can be
readily removed from the container without the user having to
insert his hands into a container and therefor without damage to
the product on the pie plate. The portion of the side wall above
the plateau is spaced from the outermost lip of the pie tin such
that it does not press against the crust of a pie in the tin or pie
filling and extends upwardly a distance to clear any topping put on
a pie.
Although a preferred form of my invention has been herein
disclosed, it is to be understood that the present disclosure is by
way of example and that variations are possible without departing
from the subject matter coming within the scope of the following
claims, which subject matter I regard as my invention.
